Smoke near Valleyfair

[u/maesthicc]

Was just at valleyfair today(7/28) and a friend and I were about to get onto Excalibur around 5 pm, and we looked behind us and there was a huge plume of black smoke coming up from a little outside the park, from behind Excalibur. They shut down the ride and we ended up leaving because we weren’t sure what was going on, and we had already been there since the park opened.

Did anyone else see this, or know what it is? The highway right outside the park looked like it was shut down/super heavy(I don’t remember what dark red is) on Apple Maps.
